T 0 all whom. it may concern:

Be it known that we, WALTER K. Voon- HEES and JOHN Osoooi), citizens ofthe United States of America, andresidents of Cedar Falls, Blackhawkcounty, Iowa, have invented certain new and useful Improvements inMachines forForming Loops in Wires, ofwhich the following is a specification. y A Our invention relates to improvements in machines for formingloops or eyes in wires, and the specific object-of our saidimprovementis to devise means whereby a loop or eye may be formed and securedpermanently in a wire end to adapt itfor fastening the wire to someother body. This object we have accomplished by the means which arehereinafterdescribed and claimed, and which are illustrated intheaccompanying drawings, in whichi Figure 1 is a plan View of 'ourimproved machine for forming loops or eyes in wires. Fig. 2 is a sideelevation of said machine with the cranks removed. Fig. 3 is a frontelevation of said machine, with parts broken away. Fig. 4 is aperspective detail View of the specific means employed in said ma chinefor forming the eye or loop in the end portion of a wire, and Fig.5 is aside elevation of said means. Fig. 6 is a perspective detail view oftheoperating device used to twist the end of the said wire about itselfafter the loop therein isformed by the other said device. Fig. 7. is aview of both said devices in theirrelative positions assumed afterforming a loo-p inthe wire end, and immediately before twisting the wireend about'itself. Fig. 8 is another position of said parts as theyrelatively appear when the second-mentioneddevice has twisted thewireend once about itself, and Fig. 9 is a third position of said partsshowing their relative positions at the end of the process of formingthe loop and securing it permanently by twisting the wire end severaltimes about itself. Fig. 10 is a view of a piece of wire having bothends permanently looped by means of our improved 'machine. Similarnumerals of reference denote cor responding. parts throughout theseveral views.

It has been found a slow and tedious process to form permanent loops oreyes in the end parts of wires by hand or with the aid only of a pair ofpliers, and it is toprovide means for rapidly and mechanically effectingthis result that we present this invention. It is our intentionparticularly to produce such loops in the ends of wires and secure themby twisting the wire end about the main body of the wire, so that thelooped ends may be of a suitable and permanent form for use in wirefences or gates, or in any other location where such a constructionwould prove useful.

The machine shown is especially adapted, by reason of having twocomplete operating devices incorporated therein in a reversed relation,to form simultaneously loops or eyes in both ends of a relatively shortpiece of wire. It is, of course, obvious that our invention is completein the assemblage and use of one; pair of the cooperating workingdevices only to form an eye or loop at a time in one end of a wire, andalso that as many of such pairs of devices may be lo- "cated andarranged in the vicinity of each other as may be necessary or useful toform eyes or loops in as many wires ranged side by side or otherwisespaced apart in juxtaposition.

The machine shown in Figs. 1 to 3 inclui sive, is one of the double typewith two reversed pairs of operating devices therein as stated, andcomprises a frame or supporting body composed of a base 1 having anintegral upright 27 supporting a flat horizontal rectangular table 2.Pairs of plates 5 and 29 of smaller dimensions and spaced apart arelocated on a plate 28 on the table 2 to leave their interspace ofsufiicient width to receive therein the gear-wheels 8 and 9, the lowerparts of the latter descending into a hollowed out part of the plate 28.Said pairs of plates on either side of said interspace are provided withcylindrical horizontal alined bearing seats adapted to receive the shaftparts 11 extending in opposite directions from and integral with thegear=wheel 9. The outer ends of the bodies 41 have integral flanges 23extending without said plates, and each provided with a detent orprojection 22 having one concave face with an obliquelydirected notch 42in its diminished extremity. 1 Both said gear-wheel 9 and both bodies llare split radially and longitudinally to a point just beyond the commonaxis of all in order to receive the wire 24 therein which is to beoperated upon, said split or groove being denoted by the numerals 10 and13.

through the upper plate 5 is in registration and communication with thegroove 43 in the other parts when said parts are rotated to have thegroove open vertically upward into said slot. The gear-wheel or pinion8, which inter-meshes with the said pinion 9, is secured on a shaft 13seated rotatably in a bearing-opening in said plates 5 and 29, and whichshaft has a hand-crank 14 secured removably on its outer end. The plates5, 28 and 29 are secured removably to the table 2 by means of the bolts6 and 7, and the screws 11. The plate 28 has two relatively narrowparallel. grooves 26 on its upper face located immediately along theouter sides of the said plates 5 and 29 and serves to receive the diskparts 23 with their projections 22 of the shaft-bodies 41.

The ends of the plate 28 just beyond the grooves 26 have verticalcylindrical orifices serving as seats for the vertical shafts 34 eachhaving on its lower end a bevel-gear wheel as is shown at 17 and 39, andthese gear-wheels both intermesh with bevel pinions 32 and 38respectively, the latter pinions being mounted on the ends of a shaft 33seated rotatably in a bearing-body 35 supported by an integral hanger.36 from a slide-body 3, which latter is slidably and adjustably seatedin a slideway formed in the table 2, and secured to said plate 28 bymeans of a screw or bolt 37. The shaft 33 extends to the right, and hasa hand-crank 16 secured thereon removably.

Upon the upper end' of each shaft 34 above the plate 28 is a rectangularbody 19, shown best in Figs. 4 and 5, and which has an axial projection21 slightly diminishing upwardly. At one side of this projection andeccentric to the axis of the shaft 34 is another projection 20 extendingupwardly, and which has one upper angle removed to provide a curved edgeor upper end. The straight vertical opposite face of said projection 20is cut away medially and transversely to form a groove 31 which latteris extended across the abutting face of the body 19 to provide a shelfthere. Just above said groove 31 a notch 30 is provided in the verticalangle of the projection 20, and which extends across the face of theprojection which is opposite the projection 21. The interspace of theprojections 20 and 21, when the body 19 is appropriately rocked lies inline with the groove 43 in the shaft-body 41. The outer 7 forwardcorners of the uppermost plate 5 are excised to provide oblique curvedsurfaces 12 for a purpose to be hereinafter described.

The successive stages of operation upon a wire 24 to form a loop in itsend or loops in both ends, and then twist the wire ends about the bodyof the wire to secure the loops permanently are as hereinafter described and as shown in Figs. 7 to 9 inclusive. These figures representthe forming of a loop in one end of a wire only, but the machine abovedescribed duplicates the same process simultaneously for both ends of apiece of wire of 'a-proper length to form a tie-wlre 24 such as showninFig. 10.

The cranks 14 and 16 are first rotated to with its projecting endsreceived between the pairs of'projections 20 and 21 on the bodies 19.The crank 16 is then, rotated in an appropriatedirection to cause bymeans of above-described gearing the bodies 19 to rotate sufficiently tocause the projections 20 to grasp the outer ends of said wire and bendit around the central projection 21. In the course of so bending thewire end as shown by the dotted lines in Fig. 1,

is brought into contact with the inclined surface 12 at the outerforward angle of the uppermost plate 5 and pushed up and back over theincline to crossv above the main body of the wire. "The crank 16 is thenrotated oppositely far enough to bring the body 19 to the position shownin Fig. 7 to clear the projection 22 when the latter is rotating,without changing the position of the wire loop about the centralprojection 21. At this point. the crank 161is. released and the crank 14is rotated in an appro-.

.priate direction to bring the projection 22 onthe disk 23 of the body4linto the position shown in said Fig. 7. A continued rotation of saidcrank in the same direction causes the projection '22 to grasp the bentover end of said wire in its notch 42, whence the wire is drawn into theconcavity ofthe face of the projection, and the projection thus holdsand forces the wire end to twist it about the main body of the wire asshown in Fig. 8. The rotation of the body 41 is continued suflicientlyto cause said project-ion 22 to twist the wire end completely with awrapping of several turns and to its extremity about the body of thewire till released, as shown'in Fig. 9. The moving parts are then insuch a relative position that the grooves aforesaid are inregistration,and the wire 24 may be lifted from them clear of the machine, theconical form of the projections 21 preventing sticking. If desired somesuitable device may be pivoted or otherwise connected to the machine soas to underlie the wire at some place of its length, and which may beoperated to lift the wire from its seat when the loops are formed andthe. ends twisted thereabout.

Attention is called to the notch30 in the projection 20 of the body 19.When this projection isbending the wire end about the other projection21, the wire end in passing over the sloping surface 12 rises untilcaught at the top of the ascent by said notch while sliding along theedge of the projection, and is held securely thereby during theremainder of the rotation of the body 19 till the loop is formed. Thegroove 31 permits the passage thereby of the projection 22 withoutinterference of said bodies.
